AW: [boost] wgcc 2.0 RC1 released

[Duft Markus]

When building with wgcc there are a few benefits:

Wgcc uses the native windows compiler to build (so the code may or may not be 
faster ;o)) and whats a lot more important: the debug information produced is 
readable by visual studio, so you can debug the output. Gdb on windows (at 
least on interix) is so terribly broken, i could not debug 10 lines of code 
without gdb failing at some point. The visual studio debugger (the 2005 version 
especially) is very very much better. (gdb on cygwin doesn't behave too good 
either. This was the initial reason for wgcc to be written (we are a 300 
programmer company ;o), we need to debug...))

With cygwin the thing is, that cygwin isn't really quite stable on win xp and 
above when using more than one CPU. I don't know how MinGW behaves there.

The second thing is, that resulting executables depend on msvcrt.lib and are 
therefore binary compatible with nearly everything ;o) on windows. When using 
gcc it has it's own libc (on interix gcc is a interix build, and has really not 
much to do with windows.... ;o//) and one can't link those things together, so 
in gcc built binaries one can _not_ use the win32 API which, on windows, is not 
really desireable.

The last thing is, that tools such as Rational Purify may be used to examine 
the resulting binaries. It's all just really native ;o)

At the moment as i wrote in my release note only Interix is supported, since 
this is also stable on win xp and above with multiple processors. But using 
cygwin as a build environment only, using wgcc as compiler is possible too, i'd 
just need to implement one method, about 5 lines of code, to convert paths from 
unix <-> windows style.

I hope this is an answer to your questions!

I'm really overwhelmed that someone outside my company finally shows at least 
_some_ interest. It's really cool, give it a try!

Cheers, Markus

I'm not sure whether this is on-topic for Boost; it seems of somewhat 
borderline relevance.  However, now that you've started the thread, one obvious 
question leaps to mind: why would anyone want to use wgcc in lieu of Cygwin or 
MinGW gcc?
